1.Zirconia all-ceramic crown and porcelain fused to metal crown for dental defects: an 8-month follow-up of periodontal conditions
Chinese Journal of Tissue Engineering Research 2015;19(30):4795-4799
BACKGROUND:Zirconia al-ceramic crown restoration has good biocompatibility and corrosion resistance, and has little irritation to the human periodontal tissue. OBJECTIVE:To compare the clinical curative effects of zirconia al-ceramic and porcelain fused to metal crowns in the repair of dental defects. METHODS: Twenty patients (120 teeth) scheduled for crown lengthening+crown repair were enroled, including 7 males and 13 females, aged 19-60 years, and then randomly divided into observation group and control group. In the observation group, zirconia al-ceramic crown was used; and in the control group, porcelain fused to metal crown was used. Periodontal conditions, coordination of gingival margin height, and crown edge concealment were compared between the two groups at 8 months after restoration. RESULTS AND CONCLUSION: At 8 months after restoration, the observation group had better periodontal conditions and crown edge concealment than the control group (P < 0.05), and the time of wearing a temporary crown and recovery time were also shorter in the observation group than the control group (P < 0.05). There was no significant difference in the gingival margin height between the two groups at 1, 3 and 8 months after restoration. These findings indicate that after crown lengthening, the zirconia al-ceramic restoration for dental defect repair has better therapeutic effects than the porcelain fused to metal restoration, which can have better marginal adaptation, improve crown edge concealment, reduce gingivitis, decrease plaque adhesion ability, and preferably maintain the periodontal health.
2.Research and Design of Medical Data Integration Platform
World Science and Technology-Modernization of Traditional Chinese Medicine 2015;17(4):916-921
In this paper, through in-depth study on characteristics of hospital information system (HIS) construction and requirements of medical data integration, and combined with the medical data straits of heterogeneity, multi-source, complexity, dynamic growth, etc., the problem of information exchange in different systems was aimed to solved, in order to realize medical data sharing among internal systems in hospital.Based on Extensible Markup Language (XML), public data model was described by XML Schema technology. Global and local medical data were queried using XQuery technology. The results showed that a medical data integration platform based on HL7 standard and the middleware technologies were proposed. It was concluded that the platform shielded the heterogeneity of underlying medical data by middleware technology. It finally realized the global query and transparent access of medical data in HIS for users.
3.Morphological analysis of autophagy.
Acta Pharmaceutica Sinica 2016;51(1):39-44
Autophagy is an important homeostatic cellular recycling mechanism responsible for degrading injured or dysfunctional subcellular organelles and proteins in all living cells. The process of autophagy can be divided into three relatively independent steps: the initiation of phagophore, the formation of autophagosome and the maturation/degradation stage. Different morphological characteristics and molecular marker changes can be observed at these stages. Morphological approaches are useful to produce novel knowledge that would not be achieved through other experimental methods. Here we summarize the morphological methods in monitoring autophagy, the principles in data interpretation and the cautions that should be considered in the study of autophagy.
4.Protective Effects of Ketorolac Tromethamine Ophthalmic Gel against Staphylococcus aureus Corneal Ulcer in Rabbits
China Pharmacy 2015;26(31):4388-4390
OBJECTIVE:To study protective effects of Ketorolac tromethamine ophthalmic gel against Staphylococcus aureus corneal ulcer in rabbits. METHODS:S. aureus corneal ulcer in rabbits model was induced by corneal substance layer inoculation, and then divided into model group,positive control group (Clarithromycin ophthalmic gel),gel high-dose,medium-dose and low-dose groups(Ketorolac tromethamine ophthalmic gel 120,80,40 mg/ml),with 20 rabbits in each group. They were given re-levant medicine,once a day for 2 weeks. The keratopathy of rabbits was observed;the clinical efficacy and keratopathy score were compared. The change of ratina was observed under micrescope. RESULTS:Compared with model group,the keratopathy score de-creased while total effective rate increased in positive control group and gel groups after medication, and the effects of gel high-dose and low-dose groups were significantly lower than that of positive control group,with statistical significance(P<0.05). The retina of rabbits had not affected by the experiment. CONCLUSIONS:Ketorolac tromethamine ophthalmic gel has protective effect against S. aureus corneal ulcer in rabbits.
5.The preventive effect of hyaluronic acid on post-surgical pelvic and abdominal adhesion
Chinese Journal of Primary Medicine and Pharmacy 2015;22(3):332-333
Objective To explore the clinical effect of sodium hyaluronic acid on prevention of post-surgical pelvic and abdominal adhesion in gynecology.Methods 336 patients with pelvic and abdominal operation,using the double blind method for the patients and doctors,were randomly divided into the observation group (172 cases)and control group(164 cases).The experimental group was given hyaluronic acid in corresponding regions of the peritoneum,and the control group was not given any tissue adhesion prevention measures.Postoperative adhesions incidence and the change of serum CRP level of two groups were recorded.Results There was significant difference between the two groups in postoperative adhesions incidence (47.5% vs 19.8%,x2 =13.10,P < 0.01).The CRP level of the observation group changed significantly as compared with the control group after operation [(24.5 ±3.4)mg/L vs(12.7 ±3.9)mg/L(t =20.86,P<0.01)].Conclusion Hyaluronic acid in prevention of postoperative adhesion of pelvic and abdominal operation is effective on improving the serum level of inflammatory factors.

9.Study on Making the Animal Model of Diarrhea-predominant Irritable Bowel Syndrome Due to Liver-Spleen Disharmony
Journal of Traditional Chinese Medicine 1993;0(06):-
Objective To explore the animal model making method for diarrhea-predominant irritable bowel syndrome (IBS-D) caused by the disharmony of liver and spleen in TCM.Methods In order to define the period of the animal model making,the 32 neonatal rats were divided into 3 days group,6 days group,9 days group and control group.In order to determine the weight of the experimental rats,the 48 rats with different weight were divided into lower weight model group,lower weight control group,medium weight model group,medium weight control group,higher weight model group and higher weight control group.In order to decide the method of causing diarrhea,the 32 rats were divided into lactose enriched diet group,restraint stress group,lactose enriched diet plus restraint stress group,and a control group.The body weight and diarrhea rate of all groups were compared respectively.After the method of model making was decided,the 16 rats were divided into a model group and a control group,and 5-hydroxytryptamin (5-HT),lactate dehydrogenase (LDH) and aquaporin 4 (AQP4) of the two groups were compared for model-proving.Results Based on the results step by step,the best method was decided:the period of the animal model making was 6 days,rats with higher body weight should be subjects,and the lactose enriched diet combining with restraint stress should be used to induce diarrhea.Model-proving test:compared with the control group,5-HT and LDH decreased (P
10.THE CLINICAL ANALYSIS OF POST-OPERATION RADIOTHERAPY ON 46 CASES OF MALIGNANT OVARIONCUS AMONG YOUNG WOMEN
Journal of Xi'an Jiaotong University(Medical Sciences) 1981;0(02):-
The paper studies the post-operation radiotherapy on 146 cases of malignant ovarioneus from 1965 to 1985. 45 cases out of 146 are young women with 27 cases of germinoma, which is 58. 6% among 46 cases. Among 27 cases of germinoma, 21 cases, that is 77%, are dysgerminoma. Because germinoma is sensitive to the radiotherapy, post-operation radiotherapy should be conducted to inerease the immortality rate, though germinoma is widely spread to lymphatic ducts. Ihe paper studies the 46 cases of malignant ovarioncus with post-operation radiotherapy and concludes that the survival rate for 5 years is 52.17% (24/46), whieh is comparatively higher than those reported in other reports.
